About Main Street:

We're solving a problem that 62% of Americans have

62% of Americans last year thought about starting a business. The #1 reason they didn’t was because they didn’t know where to start. Currents options are:

1. Going independent which is risky: no support or direction
2. Paying a franchise which is expensive:  franchises charge $100K+ fees to get started, take 10% of topline revenue, don't provide marketing support or technology

The market we're going after is bigger than e-Commerce

We’re disrupting the $2.3T franchise industry by removing the franchise fee and offering a tech-enabled franchise like product.

We’re starting with home painting where our biggest competitor is https://certapro.com/">CertaPro a $550M revenue franchise (1% market share) before quickly taking on https://www.neighborlybrands.com/our-brands/">Neighborly Brands as we expand categories (pest control, lawn care, etc.).

As we expand categories, our customer does not change

Our customer is an aspiring business owner, like https://www.linkedin.com/in/nicklaforest">Nick or https://www.linkedin.com/in/hardin-h-hawes-9ba6a72/">Hardin who doesn't care what type of business they start, as long as it is profitable. Our customers are not actually the one painting houses or completing roofing jobs, rather they are the one that hires people to do the job. Our customer has years of experience in sales and general management, which makes them suitable for any type of business — which is why as we expand to 100 categories, our customer does not change.
